About EclipseLink

EclipseLink is a persistence framework that includes also object-relational mapping (ORM),
based on Orcale's TopLink object-relational mapping product.
EclipseLink is developed in the Eclipse organization.
It is also the reference implementation of JPA 2.0.

EclipseLink is available as open source under the Eclipse Public License (EPL)
and the Eclipse Distribution License (EDL).

In this benchmark EclipseLink 2.3.2 (which was released in December 2011) has been tested.

EclipseLink Performance Tuning

The EclipseLink default configuration is generally optimized for high performance,
and works very well also with no tuning.
